i read somewhere a post by this woman who has a really old vibrator that ran off the mains, she was asking where she could get a new one from because this on shorted out everytime she had an orgasm because she was a squiter and she thought she could have a better orgasm if she could get vibrations through that....which is why they're all battery powered. I don't think I've ever seen a unit for sale that ran off AC power.
imagine! a vibrator plugged into the mains getting covered with all that liquid! i can't believe she actually carried on doing it after she survived the first time, you'd think it would make you count your blessings.
